I imagine in terms of tiles/second they'd similar. Both use mapnik as a 
backend, both use meta-tiles. Where you're likely to run into problems 
is tile expiry. The traditional mod_tile/renderd/osm2pgsql setup copes 
well with OSM data which is constantly changing. mapproxy's cache system 
doesn't have a way to handle data that is outdated except by deleting it.

That being said, I'm not sure if the normal setup handles tile expiry 
correctly in other projections.
